This means that the connectors C and D are attached to the holders J and K, one of the connectors C is fixed together with the holder J, and the other connector D together with the holder K is moved by the moving device M in FIG. Move in the -y direction,
End surfaces E and F of both connectors C and D can be abutted or separated. In this case, the end faces E and F of the connectors C and D are ground, but the end faces E and F necessarily have a curvature and the radius of curvature R is not always constant. It is difficult to make a straight line, and there may be some deviation. In addition, since there is a gap between the holders J and K and the connectors C and D for assembling them, the two are rattled, which may cause the connectors C and D to be misaligned. For this reason, the connection loss between the connectors C and D increases. Therefore, conventionally, the end faces E, F of both connectors C, D as shown in FIG.
Grease G for matching is interposed between them, and
A predetermined pressing force P by a pressing body H such as a spring.
Thus, the end face F of the movable connector D is pressed against the end face F of the fixed connector C.

と同様の問題が生じてしまう。However, in the conventional optical connector joining apparatus, since the movable side connector D is pressed at once by the pressing force P of the pressing body H, the moving speed of the movable side connector D is too fast, and the grease G is applied to both connectors C and D. In some cases, the end faces E and F abut each other before the end faces E and F are not uniformly spread. In this case, even if the grease G is used, there is a problem that the connection loss between the optical fibers A and B of the connectors C and D becomes large. To alleviate this problem, it is conceivable to reduce the pressing force P of the pressing body H to reduce the moving speed of the movable connector D by the pressing body H. Is high, it is difficult for the grease G to spread uniformly on the end surfaces E and F of the connectors C and D, and the same problem as described above occurs.

に前記した構造に限定されるものではない。1 and 2 show an embodiment of an optical connector joining apparatus according to the present invention. C and D shown in the figure are connectors to which the optical fibers A and B are attached, and J and K are holders for mounting the connectors C and D. As in the conventional case, both connectors C and D are installed so that their end faces E and F are opposed to each other. The right connector C in the figure is fixed together with its holder J, and the left connector D in the figure is The entire holder K is movable. The movable side holder K has a pressing piece N
The movable side holder K is guided by a linear guide or the like and is slid in the directions of arrows zy in FIG. G in the figure is grease interposed between the end faces E and F of both connectors C and D. In the figure, H denotes the movable side connector D and the fixed side connector C.
Side, and presses the end face F of the movable-side connector D against the end face E of the fixed-side connector C with a constant pressing force P. In this embodiment, a spring having the pressing force P of 900 gf is used. I have. M in the figure is a moving device for moving the movable side connector D together with the holder K. The moving device M corrects the drive rod T pressing the pressing piece N of the movable holder K, the rack Q connected to the drive rod T, the pinion S meshing with the rack Q, and the pinion S. And a motor (not shown) for reverse rotation. In this embodiment, the motor is rotated forward to rotate the pinion S in the direction indicated by the arrow x in FIG.
The rack Q and the drive rod T are moved in the direction indicated by the arrow t in FIG. 1 when the pinion S is rotated in the direction indicated by the arrow w in FIG. It is moved in the direction of arrow u in the figure. Reference numeral 1 denotes a speed moderator which is a feature of the present invention, and is used for moderating the moving speed of the movable connector D by the pressing body H. The speed moderator 1 of this embodiment includes a spring 1a attached to the tip of the driving rod T and an abutment 1b attached to the tip of the spring 1a. The spring 1a preferably has a spring coefficient slightly smaller than the spring coefficient of the spring of the pressing body H. In this case, the moving speed of the movable connector D by the pressing body H is moderately reduced. be able to. The connector joining apparatus of this embodiment operates as follows. First, when the motor of the moving device M rotates forward, the driving rod T is moved in the direction of the arrow t, and the spring 1a of the speed buffer 1 is pressed and contracted by the driving rod T and the pressing piece N, and The repulsive force is increased, and the spring of the pressing body H is contracted by bending to the repulsive force of the speed relaxing body 1, whereby the movable connector D is moved together with the movable holder K in the direction of the arrow z (left direction) in FIG. It is moved and separated from the fixed connector C. When the motor of the moving device M is rotated in the reverse direction from this state, the driving rod T is moved in the direction of the arrow u, and the spring 1a of the pressing body H is extended by its own restoring force.
The movable-side connector D together with the movable-side holder K approaches the fixed-side connector C as shown in FIG. When the driving rod T is further moved in the direction of arrow u from this state, the spring 1a of the speed moderator 1 is gradually extended, and accordingly, the repulsive force of the speed moderator 1 and the pressing force P of the pressing body are increased. The movable side connector D is gently pressed by the fixed side connector C by the pressing force of the difference between the two, and the grease G between the end faces E and F of both connectors C and D is gently and evenly within the time. ,
Spread between F. Further, the driving rod T is moved in the direction of the arrow u, and as shown in FIG.
When 1a extends to the initial length, the abutment of the velocity relaxation body 1
1b is separated from the pressing piece N of the movable side holder K, and the end face F of the movable side connector D has a predetermined pressing force P of the pressing body H,
That is, it is pressed against the end face E of the fixed connector C at 900 gf,
As a result, the grease G spreads uniformly over the entire surface of both ends E and F, and the optical fibers A and B of the connectors C and D are optically coupled. The structures of the moving device M and the speed moderator 1 are not particularly limited to the structures described above.
